Abstract

The invention discloses an insecticidal composition containing pyriproxyfen and tolfenpyrad. The composition is mainly characterized by comprising active components of pyriproxyfen and tolfenpyrad and the balance being an auxiliary agent; the weight ratio of the two active components pyriproxyfen and tolfenpyrad is 1:80-80:1; and the insecticidal composition can be made into wettable pulvis, water dispersible granules, a suspending agent, a suspoemulsion, an emulsion in water and a micron emulsion. The composition provided by the invention can be used to control a plurality of insects, has obvious synergism, expands insecticidal spectrum, and has high activity to cabbage caterpillar, beet armyworm, prodenia litura, whitefly, thrips, cotton bollworm, Pear psylla, scale insect and the like on vegetables, cotton, fruit trees and flowers. In addition, pesticide dosage is reduced, residual quantity of the pesticide on crops is decreased, and environmental pollution is mitigated. The insecticidal composition is safe to people and livestock and has good environmental compatibility, and insects will not easily resist the composition.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to an insecticidal composition containing pyriproxyfen and tolfenpyrad. Background technique [0002] Pyriproxyfen chemical name: 4-phenoxyphenyl (RS)-2-(2-pyridyloxy)propyl ether, molecular formula: C 20 N 19 NO 3 , pyriproxyfen is an insect growth regulator that disrupts the growth of insects with phenyl ethers. It is a new type of insecticide that is similar to juvenile hormones. It has systemic transfer activity, low toxicity, and long-lasting effect. Low toxicity, little impact on the ecological environment. It has good control effects on bemisia tabaci, scale insects, diamondback moth, beet armyworm, Spodoptera litura, pear psyllid, thrips, cotton bollworm, etc. [0003] Tolfenpyrad (Tolfenpyrad) chemical name: 4-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy)phenyl]-methyl}-1H pyrazole- 5-carboxamide, molecular formula: C 21 h 22 ClN 2 o 2 , Fenpyran is a novel pyra...
